I think you're confusing campaigning with saying, and compulsion with ostracism. You're not talking about free speech, you're talking about freedom from consequences. If you truly believe all political speech should be considered equal, I suggest you upvote this comment. And yes, some forms of speech can be used to close down other speech. Online harassment is an obvious example but I seriously doubt it's what you had in mind. Incidentally, the answer to your above questions is: in many states, actually, they do. If that's something that concerns you, maybe campaign to make that illegal.
